carbon filter/fan question...

[Sleepy]

hello...can you help me?

i need to know what filter/fan combo i would need for the following indoor space:

4 feet by 8 feet by 9 feet high...288 cubic feet.

i want one thing to plug in and i want it to be as easy as possible.

any help is appreciated.

i'm guessing refreshing the air @ 1-3 minutes any combo that would do at least 300 cfm should take care of any odor issues. my room is 1372 cf, and i'm running a can 50 with a 424 cfm fan. adjusting for pressure loss i'm changing the air about very 4 minutes. not ideal but i cant afford a new fan right now. i do hear the mountain air filters are good, the can filters are good also. just stay away from growbright filters.

I found this elswhere, but it answers your question.

If you are not sure what size extractor fan to use, it's easy to work out. Simply calculate the volume of the growing environment to the nearest cubic metre. This is done by multiplying:

Length x Width X Height = Volume of your room in cubic metres (m³) and then multiply the answer by 20.

Ideally, air needs to be replaced every three minutes (or twenty times an hour). Therefore, just multiply the volume of your growroom by 20. Measure the height, width and length of your room.


For example, a room of 3 metres x 4 metres x 2.5 metres high = 30m³ and 30m³ x 20 changes per hour = 600m³ per hour. Once this has been calculated, you can select the correct fan.

I've been looking into the same thing, you might want to check the feedback from folkson what I asked in this room.

Depends on the Stink Factor and your CFM..

LOL


Oh well...

so 133cfm would do a 36Wx18Dx49H

Hi Sleepy,

Your ventilation needs for the 288 cuft room is between 1 and 5 Minutes per Air Change.

288 / 1 = 288 CFM for 1 Min/AC
288 / 3 = 96 CFM for 3 Min/AC
288 / 5 = 58 CFM for 5 Min/AC





Here are the fan/filter curves for the CANFAN lineup. I'd say a 4" fan matched up with a 9000 would be the best.

i got it hooked up, hung from the ceiling and it is doing a super good job!

thanks redgreenery!!

i'll get some pics of her in action later this week!!

K+++++++

working very well...

working very well...

here are a few pics of the fan/filter in action.

no big deal for most of you guys/gals, but the vaportek just wasn't cutting it any more.

i left the vaportek on for the first few daze, then turned it off entirely...

still no smell coming form the grow!!

woot!!



thanks again, redgreenery!

 

[whodair]

is that a 6 inch combo ?? how much light you cooling ?? 6 in fan/filter seems to handle 600w hps in the average tent/closet...with a speed controller to slow her down when the ambient temps drop...

 

[Sleepy]

nope...not cooling any lights with this...just killing the odor.

4 inch HO fan with a matching 4 inch flange. fits perfectly onto the fan, and a perfect fit for my space.
